Description
Schaltungsanordnung zur Ansteuerung von Elektromagneten Die Erfindung betrifft eine Schaltungsanordnung zur Ansteuerung von Elektromagneten mit unterschiedlichen Anzugs- und Halte strömen mittels Halbleiterbauelementen.Circuit arrangement for controlling electromagnets The invention relates to a circuit arrangement for controlling electromagnets with different Pull-in and hold-in flows by means of semiconductor components.
Bei bekannten Schaltungsanordnungen wird der Elektromagnet für den eigentlichen Anzugsvorgang mit einem relativ großen Strom, der nur während des Anzugsvorganges wirksam ist, beaufschlagt. Demgegenüber kann der Strom, der nach erfolgtem Anzug als Halte strom wirksam ist, wesentlich geringer sein, um noch mit genügender Sicherheit den Elektromagneten im angezogenen Zustand verharren zu lassen. Zu diesem Zweck wird bei bekannten Anordnungen für den Anzuga- und Haltestrom Je ein eigener Verstärker verwendet, deren Eingänge mit den Anzugs- bzw. Halte impulsen beaufschlagt werden. Die Verringerung des Halte stromes gegenüber dem Anzugsstrom wird dabei durch Vorschalten eines Widerstandes vor die Erregerwicklung erreicht.In known circuit arrangements, the electromagnet for the actual tightening process with a relatively large current that only occurs during the tightening process is effective, applied. On the other hand, the current, which after a tightening when holding current is effective, it will be much lower in order to still be sufficiently safe to let the electromagnet remain in the attracted state. To this end in known arrangements for the pick-up and holding current each has its own amplifier are used, the inputs of which are supplied with the pick-up or holding pulses. The reduction in the holding current compared to the pick-up current is achieved by connecting upstream one Resistance reached in front of the excitation winding.
Weiterhin ist bekannt, die geringere Halteeregung durch eine zusätzlich zur Anzugswicklung aufgebrachte, entsprechend dimensionierte Haltewicklung zu realisieren.It is also known that the lower holding excitation by an additional to implement appropriately dimensioned holding winding applied to the pull-in winding.
Die Nachteile der bekannten Schaltungsanordnungen sind, daß zwei getrennte Verstärker benötigt werden, daß bei der ersten bekannten Anordnung während des Haltezustandes eine hohe Verlustleistung im Vorwiderstand auftritt und daß bei der zweiten bekannten Anordnung ein erhöhter Wickelraumbedarf infolge der zweiten Wicklung notwendig ist.The disadvantages of the known circuit arrangements are that two separate Amplifiers are needed that in the first known arrangement during the hold state a high power loss occurs in the series resistor and that in the second known Arrangement an increased winding space requirement is necessary due to the second winding.
Der Zweck der Erfindung ist, die Nachteile der vorgenannten Schaltungsanordnungen zu vermeiden.The purpose of the invention is to overcome the disadvantages of the aforementioned circuit arrangements to avoid.
Der Erfindung liegt die Aufgabe zugrunde, eine derartige Schaltungsanordnung zur Ansteuerung von Elektromagneten zu schaffen, die die Ansugs- und Halteerregung mit einem einzigen Verstärker realisiert.The invention is based on the object of such a circuit arrangement to control electromagnets to create the suction and holding excitation realized with a single amplifier.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß für die Anzugs und Halteerregung des Elektromagneten ein gemeinsamer Verstärker und eine gemeinsame Wicklung vorgesehen ist, daß das Eingangssignal des Verstärker. für den Haltestrom so in Einzelimpulse aufgelöst ist, daß der arithietisohe Mittelwert des in der Wicklung fließenden Ispulsstromes dem geforderten Kalte strom entspricht. Weitere Merkmale einer besonderen Ausgestaltung der erfindungsgemäßen Lösung der Aufgabe ergeben sich aus den Unteransprüohen.According to the invention the object is achieved in that for the suit and holding excitation of the electromagnet a common amplifier and a common Winding is provided that the input signal of the amplifier. for the holding current is resolved into single pulses so that the arithmetic mean value of the in the winding the flowing pulse current corresponds to the required cold current. Other features result in a special embodiment of the inventive solution to the problem from the subclaims.
Die Vorteile der erfindungsgemäßen Lösung bestehen darin, daß ein gemeinsamer Verstärker und eine gemeinsame Wicklung für die Anæugs- und Halteerregung verwendet wird, daß ein Widerstand für die Verringerung des Halte stromes entfällt, wodurch Verlustleistungen bei längeren Haltezeiten vermieden werden und daß der Haltestrom kontinuierlich durch eine Änderung des Tastverhältnisses der Ansteuerimpulse einstellbar ist.The advantages of the solution according to the invention are that a common amplifier and a common winding for the anæugs- and hold excitation is used that a resistor for reducing the holding current is omitted, whereby power losses are avoided with longer holding times and that the Holding current continuously by changing the duty cycle of the control pulses is adjustable.
Die Erfindung wird nachstehend an einem Ausführungsbeispiel näher erläutert. In der zugehörigen Zeichnung zeigen: Fig. 1: ein Blockschaltbild der getasteten Halteerregung von Elektromagneten, Big. 2s die Impulsformen der erfindungsgemäßen Schaltungsanordnung nach Big. 1.The invention is explained in more detail below using an exemplary embodiment explained. The accompanying drawings show: FIG. 1: a block diagram of the keyed holding excitation of electromagnets, Big. 2s the pulse shapes of the invention Circuit arrangement according to Big. 1.
Der Anzugsimpuls 1 (Fig. 1) steuert den Elektromagneten 7 über den Oder-Knoten 5 und den Verstärker 6 an.The attraction pulse 1 (Fig. 1) controls the electromagnet 7 via the OR node 5 and the amplifier 6.
Nachdem der Anzug des Elektromagneten 7 beendet ist, wird der kleinere Haltestrom dadurch erzeugt, daß der Halte impuls 2 durch den Multivibrator 3 und den Und-Knoten 4 in Einzelimpulse (Fig. 2) mit einem solchen vom Multivibrator 3 bestimmten Tastverbältnis aufgelöst und über den Oder-Knoten 5 dem Verstärker 6 als Eingangssignal 9 zugeführt wird, daß der arithmetische Mittelwert des in der Wicklung des Elektromagneten 7 fließenden Spulenstrones 10 dem gewiliwohten Halte strom entspricht.After the attraction of the electromagnet 7 is finished, the smaller one Holding current generated in that the holding pulse 2 through the multivibrator 3 and the AND node 4 in single pulses (Fig. 2) with one from the multivibrator 3 certain tactile relationship resolved and via the OR node 5 to the amplifier 6 is supplied as input signal 9 that the arithmetic mean of the in the Winding of the electromagnet 7 flowing coil current 10 the intended hold electricity corresponds.
